Levymatriisi
Levymatriisi, also known as a plate matrix or stiffness matrix, is a fundamental concept in structural analysis, particularly in the finite element method. It describes the relationship between forces and displacements within a thin plate. Imagine a flat, relatively thin structure subjected to external loads. Levymatriisi mathematically encapsulates how the plate will deform and the internal forces that will arise in response to these loads.
Specifically, a levymatriisi is derived by considering the plate's material properties, such as its Young's modulus
Solving the equation formed by multiplying the levymatriisi by the nodal displacement vector and equating it
